A Young, Meek Woman Travels To A Foreign Land But Accidentally Kills An Older Woman

Riddle: A young, meek woman travels to a foreign land but accidentally kills an older woman when she arrives there. The young woman is very surprised to hear only cheers and praise from the large group of witnesses to the older woman's death ------ in fact, the entire group honors and thanks her for the killing. But the story doesn't end there, as the young woman later teams up with three males who agree to assist her in attempting to murder the sister of the dead woman. Having developed a taste for blood, the young woman, with the help of her gang of three males, manages to murder the second sister, much to the delight of an oddly dressed battalion of soldiers. This young woman is never tried for either of the killings and eventually, she returns home. What kind of warped justice is this? Two killings ------ one a definite murder, and not even an indictment? What in the world is going on here?
